I had this same problem trying to connect to the internet
using broadband cable. The browser window was blank with
that error on the bottom. After trying to troubleshoot the
problem with the cable company, They determined that
Winsock was corupted. To resolve it:
1. Remove TCPIP from Network Properties
2. Open regedit and go to
HKLM/System/CurrentControlSet/Services and Delete the
Winsock and Winsock2 folder.
3. Reinstall TCP/IP protocol
Good Luck
